Hi,
I asked this question on freebsd-questions a couple of weeks ago, got a
couple of answers and then I was away from work for a couple of weeks.
One answer that I got suggested that I ask this forum, so here goes:
I have a standard Dell Poweredge 2300 running FreeBSD 3.1.
When running cvsup on this machine, the kernel crashes every time about a
minute after starting cvsup.
The kernel that was used in generating the following traces and dmesg
output, is a custom kernel, but the problem is just as reproduceable with
the Generic kernel.
I have checked the disks using the utility built in to the Adaptec
controller, but this has not revealed any problems with the disks.
I have checked the bug database at freebsd.org, and there are a couple of
references to similar crashes, but no recommended fixes or patches. I cannot
build a current kernel as I can't get cvsup to copy the files over, so I am
interested if anyone knows what causes this problem, and if there are any
known fixes or workarounds.
Thanks
Kevin Quinlan
